Florida- By Alicja (Lily) Fisher- Period 2.

Name of the Fossil

*Cnidaria anthozoa

Description of the Organism

*This coral was actually composed by the remains of polyps, and their skeletons.
*Polyps are small ocean animals.
*They gather underwater on hard surfaces, and combine the lime in seawater (which is warm) with carbon dioxide; found in their bodies, which thus forms coral, or a hard lime-stone like texture.
*This process usually takes around 20-30 million years.

Time Existed

*This existed 30-40 million years ago.
*That time period was when Florida was part of the continental shelf.
*The oceans were filled with various different small organisms that contributed to the surfacing of coral.
*These oceans and seas were vast.

Preservation

*The coral had been preserved because it was created by sea life.
*The silica in the ocean water replaced the lime in the coral, producing quartz mineral which preserved the coral, and changed it to a chalcedony; which furthermore resulted in
pseudomorph forming.

Who Found this Fossil/Why is it the State Fossil

*The founder of this fossil is not know, although these fossils can be found in the areas of Tampa Bay, the Econfina River, and the Withlacoochee/Suwannee River beds.
*This is the state fossil because millions of years in the past florida used to be surrounded by vast oceans which harbored the polyps which produced these types of coral.
*This fossil is recognized as being special because it went through a long process of pseudomorph, which exchanged the current minerals in it with ones inside the ocean and environment surrounding.
